Improvements in Diet and Physical Activity-Related Psychosocial Factors Among African Americans Using a Mobile Health Lifestyle Intervention to Promote Cardiovascular Health: The FAITH! (Fostering African American Improvement in Total Health) App Pilot Study

BACKGROUND

African Americans continue to have suboptimal cardiovascular health (CVH) related to diet and physical activity (PA) behaviors compared with White people. Mobile health (mHealth) interventions are innovative platforms to improve diet and PA and have the potential to mitigate these disparities. However, these are understudied among African Americans.

OBJECTIVE

This study aims to examine whether an mHealth lifestyle intervention is associated with improved diet and PA-related psychosocial factors in African Americans and whether these changes correlate with diet and PA behavioral change.

METHODS

This study is a retrospective analysis evaluating changes in diet and PA-related self-regulation, social support, perceived barriers, and CVH behaviors (daily fruit and vegetable intake and moderate-intensity PA [MPA] per week) in 45 African American adults (mean age 48.7 years, SD 12.9 years; 33/45, 73% women) enrolled in the FAITH! (Fostering African American Improvement in Total Health) app pilot study. The intervention is a 10-week, behavioral theory-informed, community-based mHealth lifestyle intervention delivered through a mobile app platform. Participants engaged with 3 core FAITH! app features: multimedia education modules focused on CVH with self-assessments of CVH knowledge, self-monitoring of daily fruit and vegetable intake and PA, and a sharing board for social networking. Changes in self-reported diet and PA-related self-regulation, social support, perceived barriers, and CVH behaviors were assessed by electronic surveys collected at baseline and 28 weeks postintervention. Changes in diet and PA-related psychosocial factors from pre- to postintervention were assessed using paired 2-tailed t tests. The association of changes in diet and PA-related psychosocial variables with daily fruit and vegetable intake and MPA per week was assessed using Spearman correlation. Associations between baseline and 28-week postintervention changes in diet and PA-related psychosocial measures and CVH behaviors with covariates were assessed by multivariable linear regression.

RESULTS

Participants reported improvements in 2 subscales of diet self-regulation (decrease fat and calorie intake, P=.01 and nutrition tracking, P<.001), one subscale of social support for healthy diet (friend discouragement, P=.001), perceived barriers to healthy diet (P<.001), and daily fruit and vegetable intake (P<.001). Improvements in diet self-regulation (increase fruit, vegetable, and grain intake, and nutrition tracking) and social support for healthy diet (friend encouragement) had moderate positive correlations with daily fruit and vegetable intake (r=0.46, r=0.34, and r=0.43, respectively). A moderate negative correlation was observed between perceived barriers to healthy diet and daily fruit and vegetable intake (r=-0.25). Participants reported increases in PA self-regulation (P<.001). Increase in social support subscales for PA (family and friend participation) had a moderate positive correlation with MPA per week (r=0.51 and r=0.61, respectively).

CONCLUSIONS

Our findings highlight key diet and PA-related psychosocial factors to target in future mHealth lifestyle interventions aimed at promoting CVH in African Americans.

Association of body image dissatisfaction, behavioral responses for healthy eating, and cardiovascular health in African-American women with overweight or obesity: A preliminary study

BACKGROUND

African-American (AA) women have the lowest prevalence of ideal categorizations of diet and body mass index (BMI), as defined by the American Heart Association (AHA) Life's Simple 7 (LS7) cardiovascular health (CVH) components compared to other racial/ethnic groups, regardless of sex/gender. There is limited research exploring the interplay of unique psychosocial influences on CVH such as body image dissatisfaction (BID) and behavioral responses for healthy eating among AA women with overweight or obesity.

OBJECTIVE

This study aimed to assess the association of BID with behavioral responses for healthy eating and LS7 components.

METHODS

A cross-sectional analysis of baseline data was conducted among 32 AA women with overweight or obesity from a larger, community-based participatory research study. Self-reported measures were used to assess BID and behavioral responses to healthy eating (diet self-regulation to reduce fat or caloric intake and motivation for healthy eating [intrinsic motivation and integrated regulation]) using previously validated instruments. The LS7 components (e.g., BMI, diet, etc.) and composite score were evaluated using the AHA LS7 metrics rubric.

RESULTS

Women with no or lower BID had greater diet self-regulation to reduce fat or caloric intake (mean, 3.5 vs 3.0; P=.05), intrinsic motivation for healthy eating (mean, 5.3 vs 4.2; P=.01), and integrated regulation for healthy eating (mean, 5.3 vs 3.7; P=.002) than those with higher BID. These significant differences remained after adjustment for BMI. Women with higher BID had a higher proportion of BMI within the obesity range compared with those with no or lower BID (94.4% vs 57.1%, P=.03). BID was not significantly associated with other LS7 components or composite score.

CONCLUSION

BID and other psychosocial influences for healthy eating are potential targets for culturally tailored lifestyle interventions among AA women.

Associations Between Social Determinants and Hypertension, Stage 2 Hypertension, and Controlled Blood Pressure Among Men and Women in the United States

BACKGROUND

Social determinants influence the development and control of hypertension.

METHODS

National Health and Nutrition Examination Survey (2011-2018) data for adults aged ≥18 included education, income, employment, race/ethnicity, healthcare access, marital status, and nativity status. Outcomes were hypertension (blood pressure [BP] ≥130/80 mm Hg or self-reported hypertension medication use), stage 2 hypertension (BP ≥140/90 mm Hg), and controlled BP (BP <130/80 mm Hg among those with hypertension). Poisson regression with robust variance estimates was used to examine associations between social determinants and outcomes, by sex.

RESULTS

The analysis included 21,664 adults (mean age 47.1 years), of whom 51% were women. After adjustment, hypertension and stage 2 hypertension prevalence remained higher among Black and Asian than White adults, regardless of sex. Blacks had lower prevalence of controlled BP than Whites. Compared with college graduates, men and women with less education had a higher prevalence of hypertension and stage 2 hypertension. Men (prevalence ratio [PR]: 0.28, 95% confidence interval: 0.16-0.49) and women (PR: 0.44, 0.24-0.78) with no routine place for healthcare had lower prevalence of controlled BP than those who had a routine place for healthcare. Uninsured men (PR: 0.66, 0.44-0.99) and women (PR: 0.67, 0.51-0.88) had lower prevalence of controlled BP than those insured. Unemployed or unmarried women were more likely to have controlled BP than employed or married women.

CONCLUSIONS

Social determinants were independently associated with hypertension outcomes in US adults. Policy interventions are urgently needed to address healthcare access and education, and eliminate racial disparities.

Testimonial Injustice: Linguistic Bias in the Medical Records of Black Patients and Women

BACKGROUND

Black Americans and women report feeling doubted or dismissed by health professionals.

OBJECTIVE

To identify linguistic mechanisms by which physicians communicate disbelief of patients in medical records and then to explore racial and gender differences in the use of such language.

DESIGN

Cross-sectional.

SETTING/PARTICIPANTS

All notes for patients seen in an academic ambulatory internal medicine practice in 2017.

MAIN MEASURES

A content analysis of 600 clinic notes revealed three linguistic features suggesting disbelief: (1) quotes (e.g., had a "reaction" to the medication); (2) specific "judgment words" that suggest doubt (e.g., "claims" or "insists"); and (3) evidentials, a sentence construction in which patients' symptoms or experience is reported as hearsay. We used natural language processing to evaluate the prevalence of these features in the remaining notes and tested differences by race and gender, using mixed-effects regression to account for clustering of notes within patients and providers.

KEY RESULTS

Our sample included 9251 notes written by 165 physicians about 3374 unique patients. Most patients were identified as Black (74%) and female (58%). Notes written about Black patients had higher odds of containing at least one quote (OR 1.48, 95% CI 1.20-1.83) and at least one judgment word (OR 1.25, 95% CI 1.02-1.53), and used more evidentials (β 0.32, 95% CI 0.17-0.47), compared to notes of White patients. Notes about female vs. male patients did not differ in terms of judgment words or evidentials but had a higher odds of containing at least one quote (OR 1.22, 95% CI 1.05-1.44).

CONCLUSIONS

Black patients may be subject to systematic bias in physicians' perceptions of their credibility, a form of testimonial injustice. This is another potential mechanism for racial disparities in healthcare quality that should be further investigated and addressed.

Abstract 048: Disparities In Gestational Diabetes Mellitus Among US- Vs. Foreign-born Women: An Analysis Of 2016-2017 National Health Interview Survey

Background: Gestational diabetes mellitus (GDM) is a common complication of pregnancy. Although GDM is associated with increased risk of cardiovascular disease it is unclear whether the associations between GDM prevalence and cardiometabolic risk factors differ between US- and foreign-born women and whether length of US residence influences these associations.

Methods: We analyzed cross-sectional data from the 2016-2017 National Health Interview Survey among women currently living in the US who both reported ever being pregnant and responded to the survey question about GDM. Using generalized linear models with binomial distribution and logit link, we examined the prevalence of GDM by nativity status and length of US residence adjusting for potential confounders (Table).

Results: Of 24,466 women, 14.3% were foreign-born. The crude prevalence of GDM was higher among foreign-born (9.0%) compared to US-born women (7.1%). Foreign-born women with ≥10 years of residence in the US had the highest age-standardized GDM prevalence (8.3%) compared to US-born (7.5%) and foreign-born women with <10 years US residence (4.8%). Among women with a history of GDM, US-born women were more likely to be overweight/ obese, report a history of hypertension, be current smokers and alcohol drinkers than foreign-born women. Among foreign-born women, those with ≥10 years of US residence had higher prevalence of hypertension, smoking and alcohol use than those with <10 years in the US. In the fully adjusted regression model, only foreign-born women with ≥10 years of residence in the US had a significantly higher prevalence of GDM than US-born women (PR=1.43; 95% CI:1.22-1.67).

Conclusions: In this sample of women with self-reported GDM, greater length of US residence contributes to nativity-related disparities in GDM. Acculturation, including changing health-related behaviors, may have a larger impact on maternal health outcomes of foreign-born women, and should be a target of interventions to reduce GDM and future cardiovascular diseases.

The editorialists discuss the findings as well as strategies to improve the effectiveness of public health messages.

Social Determinants of Health as Potential Influencers of a Collaborative Care Intervention for Patients with Hypertension

Objectives

The use of collaborative care teams, comprising nurse care managers and community health workers, has emerged as a promising strategy to tackle hypertension disparities by addressing patients' social determinants of health. We sought to identify which social determinants of health are associated with a patient's likelihood of engaging with collaborative care team members and with the nurse care manager's likelihood of enlisting community health workers (CHW) to provide additional support to patients.

Methods

We conducted a within-group longitudinal analysis of patients assigned to receive a collaborative care intervention in a pragmatic, cluster randomized trial that aims to reduce disparities in hypertension control (N=888). Generalized estimating equations were used to identify which social determinants of health, reported on the study's baseline survey, were associated with the odds of patients engaging with the collaborative care intervention, and of nurses deploying community health workers.

Results

Patients who were unable to work and those with higher health literacy were less likely to engage with the collaborative care team than those who were employed full time or had lower health literacy, respectively. Patients had a greater likelihood of being referred to a community health worker by their care manager if they reported higher health literacy, perceived stress, or food insecurity, while those reporting higher numeracy had lower odds of receiving a CHW referral.

Implications/Conclusions

A patient's social determinants of health influence the extent of engagement in a collaborative care intervention and nurse care manager appraisals of the need for supplementary support provided by community health workers.

Association of Perceived Stress and Discrimination on Medication Adherence among Diverse Patients with Uncontrolled Hypertension

Background

Uncontrolled hypertension is a significant risk factor for cardiovascular morbidity and mortality. In the United States, many patients remain uncontrolled, in part, due to poor medication adherence. Efforts to improve hypertension control include not only attending to medical management of the disease but also the social determinants of health, which impact medication adherence, and ultimately blood pressure control.

Purpose

To determine which social determinants - health care access or community and social stressors - explain medication adherence.

Methods

In this cross-sectional analysis, we used baseline data (N=1820, collected August 2017 to October 2019) from a pragmatic trial, which compares the effectiveness of a multi-level intervention including collaborative care and a stepped approach with enhanced standard of care for improving blood pressure. We used logistic regression analyses to examine the association between patient experiences of care and community and social stressors with medication adherence.

Results

The participants represented a diverse sample: mean age of 60 years; 59% female; 57.3% Black, 9.6% Hispanic, and 33.2% White. All participants had a blood pressure reading ≥140/90 mm Hg (mean blood pressure - 152/85 mm Hg). Half of the participants reported some level of non-adherence to medication. Regression analysis showed that, compared with Whites, Blacks (AOR .47; 95% CIs: .37-.60, P<.001) and Hispanics (AOR .48; 95% CIs: .32- .73, P<.001) were less likely to report medication adherence. Also part-time workers (AOR .57; 95% CIs: .38-.86, P<.05), and those who reported greater perceived stress (AOR .94; 95% CIs: .91 - .98, P<.001) and everyday discrimination (AOR .73; 95% CIs: .59 - .89; P<.001) had lower odds of medication adherence. Among Blacks, greater perceived stress (AOR .93; 95% CIs: .88-.98, P<.001) and everyday discrimination (AOR .63; 95% CIs: .49 - .82, P<.005) were negatively associated with medication adherence. Among Hispanics, greater report of everyday discrimination (AOR .36; 95% CIs: .14 - .89, P<.005) was associated with lower odds of medication adherence. Among Whites, the negative effect of perceived stress on medication adherence was attenuated by emotional support.

Conclusions

Using the social determinants of health framework, we identified associations between stress, everyday discrimination and medication adherence among non-Hispanic Blacks and Hispanics that were independent of health status and other social determinants. Programs to enhance self-management for African American and Hispanic patients with uncontrolled blood pressure should include a specific focus on addressing social stressors.

Can Community Health Workers Increase Palliative Care Use for African American Patients? A Pilot Study

PURPOSE

African American patients with cancer underutilize advance care planning (ACP) and palliative care (PC). This feasibility study investigated whether community health workers (CHWs) could improve ACP and PC utilization for African American patients with advanced cancer.

METHODS

African American patients diagnosed with an advanced solid organ cancer (stage IV or stage III disease with a palliative performance score < 60%) were enrolled. Patients completed baseline surveys that assessed symptom burden and distress at baseline and 3 months post-CHW intervention. The CHW intervention consisted of a comprehensive assessment of multiple PC domains and social determinants of health. CHWs provided tailored support and education on the basis of iterative assessment of patient needs. Intervention feasibility was determined by patient and caregiver retention rate above 50% at 3 months.

RESULTS

Over a 12-month period, 24 patients were screened, of which 21 were deemed eligible. Twelve patients participated in the study. Patient retention was high at 3 months (75%) and 6 months (66%). Following the CHW intervention, symptom assessment as measured by Edmonton Symptom Assessment System improved from 33.8 at baseline to 18.8 (P = .03). Psychological distress improved from 5.5 to 4.7 (P = .36), and depressive symptoms from 42.2 to 33.6 (P = .09), although this was not significant. ACP documentation improved from 25% at baseline to 75% at study completion. Sixty-seven percentage of patients were referred to PC, with 100% of three decedents using hospice.

CONCLUSION

Utilization of CHWs to address PC domains and social determinants of health is feasible. Although study enrollment was identified as a potential barrier, most recruited patients were retained on study.

A Cardiovascular Health and Wellness Mobile Health Intervention Among Church-Going African Americans: Formative Evaluation of the FAITH! App

BACKGROUND

In light of the scarcity of culturally tailored mobile health (mHealth) lifestyle interventions for African Americans, we designed and pilot tested the Fostering African-American Improvement in Total Health (FAITH!) App in a community-based participatory research partnership with African American churches to promote cardiovascular health and wellness in this population.

OBJECTIVE

This report presents the results of a formative evaluation of the FAITH! App from participants in an intervention pilot study.

METHODS

We included 2 semistructured focus groups (n=4 and n=5) to explore participants' views on app functionality, utility, and satisfaction as well as its impact on healthy lifestyle change. Sessions were audio-recorded and transcribed verbatim, and qualitative data were analyzed by using general inductive analysis to generate themes.

RESULTS

In total, 6 overarching themes emerged among the 9 participants: overall impression, content usefulness, formatting, implementation, impact, and suggestions for improvement. Underpinning the themes was a high level of agreement that the intervention facilitated healthy behavioral change through cultural tailoring, multimedia education modules, and social networking. Suggestions for improvement were streamlining the app self-monitoring features, prompts to encourage app use, and personalization based on individuals' cardiovascular risk.

CONCLUSIONS

This formative evaluation found that the FAITH! App had high reported satisfaction and impact on the health-promoting behaviors of African Americans, thereby improving their overall cardiovascular health. Further development and testing of the app among African Americans is warranted.

Enhancing Community Engagement by Schools and Programs of Public Health in the United States

The US Centers for Disease Control and Prevention define community engagement as "the process of working collaboratively with and through groups of people" in order to improve their health and well-being. Central to the field of public health, community engagement should also be at the core of the work of schools and programs of public health. This article reviews best practices and emerging innovations in community engagement for education, for research, and for practice, including critical service-learning, community-based participatory research, and collective impact. Leadership, infrastructure, and culture are key institutional facilitators of successful academic efforts. Major challenges to overcome include mistrust by community members, imbalance of power, and unequal sharing of credit. Success in this work will advance equity and improve health in communities all around the world.

Social network factors and cardiovascular health among baltimore public housing residents

Social networks - or the web of relationships between individuals - may influence cardiovascular disease risk, particularly in low-income urban communities that suffer from a high prevalence of cardiovascular disease. Our objective was to describe the social networks of public housing residents - a low-income urban population - in Baltimore, MD and the association between these networks and blood pressure. We used cross-sectional survey data of randomly selected heads of household in two public housing complexes in Baltimore, MD (8/2014-8/2015). Respondents answered questions about 10 social network members, including attributes of their relationship and the frequency of interaction between members. We calculated measures of network composition (e.g., proportion of network members who were family members) and network structure (e.g., density), which we then dichotomized as "high" (upper quartile) and "low" (less than upper quartile). We used linear regression to test the association between network measures and mean systolic and diastolic blood pressure. The sample included 259 respondents (response rate: 46.6%). Mean age was 44.4 years, 85.7% were women, 95.4% Black, and 56.0% had a history of hypertension. A high proportion of older children (age 8-17 years) in the network (>30%) was associated with a 4.0% (95%CI [0.07, 8.07], p = 0.047) higher mean systolic blood pressure (~4.9 mmHg greater). Other network attributes had no association with blood pressure. Social network attributes, such as having a high proportion of older children in one's network, may have particular relevance to blood pressure among low-income public housing residents, reinforcing the potential importance of social relationships to cardiovascular health.

Discrimination Is Associated with Elevated Cardiovascular Disease Risk among African Immigrants in the African Immigrant Health Study

Background

African Americans and other persons of African descent in the United States are disproportionately affected by cardiovascular diseases (CVD). Discrimination is associated with higher CVD risk among US adults; however, this relationship is unknown among African immigrants.

Methods

The African Immigrant Health Study was a cross-sectional study of African immigrants in Baltimore-Washington, DC, with recruitment and data collection taking place between June 2017 and April 2019. The main outcome was elevated CVD risk, the presence of ≥3 CVD risk factors including hypertension, diabetes, high cholesterol, overweight/obesity, tobacco use, and poor diet. The secondary outcomes were these six individual CVD risk factors. The exposure was discrimination measured with the Everyday Discrimination Scale; summed scores ≥2 on each item indicated frequent experiences of discrimination. Resilience was assessed with the 10-item Connor-Davidson resilience scale. Logistic regression was used to examine the odds of elevated CVD risk, adjusting for relevant covariates.

Results

We included 342 participants; 61% were females. The mean (±SD) age was 47(±11) years, 61% had at least a bachelor's degree, 18% had an income <$40,000, and 49% had lived in the US ≥15 years. Persons with frequent experiences of discrimination were 1.82 times (95%CI: 1.04-3.21) more likely to have elevated CVD risk than those with fewer experiences. Resilience did not moderate the relationship between CVD risk and discrimination.

Conclusion

African immigrants with frequent experiences of discrimination were more likely to have elevated CVD risk. Targeted and culturally appropriate interventions are needed to reduce the high burden of CVD risk in this population. Health care providers should be aware of discrimination as a meaningful social determinant of CVD risk. At the societal level, policies and laws are needed to reduce the occurrence of discrimination among African immigrants and racial/ethnic minorities.

Historical Insights on Coronavirus Disease 2019 (COVID-19), the 1918 Influenza Pandemic, and Racial Disparities: Illuminating a Path Forward

The coronavirus disease 2019 (COVID-19) pandemic is exacting a disproportionate toll on ethnic minority communities and magnifying existing disparities in health care access and treatment. To understand this crisis, physicians and public health researchers have searched history for insights, especially from a great outbreak approximately a century ago: the 1918 influenza pandemic. However, of the accounts examining the 1918 influenza pandemic and COVID-19, only a notable few discuss race. Yet, a rich, broader scholarship on race and epidemic disease as a "sampling device for social analysis" exists. This commentary examines the historical arc of the 1918 influenza pandemic, focusing on black Americans and showing the complex and sometimes surprising ways it operated, triggering particular responses both within a minority community and in wider racial, sociopolitical, and public health structures. This analysis reveals that critical structural inequities and health care gaps have historically contributed to and continue to compound disparate health outcomes among communities of color. Shifting from this context to the present, this article frames a discussion of racial health disparities through a resilience approach rather than a deficit approach and offers a blueprint for approaching the COVID-19 crisis and its afterlives through the lens of health equity.

Protecting the vulnerable during COVID-19: Treating and preventing chronic disease disparities

The coronavirus disease 2019 (COVID-19) pandemic has exacerbated health disparities across ethnic and socioeconomic groups. Non-communicable diseases (NCDs) - such as hypertension, diabetes, and obstructive lung diseases – are key drivers of this widening gap, because they disproportionately afflict vulnerable populations.

Vulnerable populations with non-communicable diseases, in turn, are disproportionately affected by COVID-19 itself – but also at increased risk of poor outcomes from those underlying conditions. Proven strategies for NCD control must be adapted to help vulnerable patients react to these dual threats. We detail six key policy interventions – task shifting, workforce protection, telehealth and mobile services, insurance restructuring and increased funding for NCDs, prescription policies for NCDs and community partnerships - to bridge this care gap. Long-term integration of these care models post-COVID-19 may prevent care shocks during future pandemics, bolstering emerging universal primary care models.

National Trends in the Association of Race and Ethnicity With Predialysis Nephrology Care in the United States From 2005 to 2015

Importance

Predialysis nephrology care is associated with better survival among patients with end-stage kidney disease.

Objective

To examine national trends in racial/ethnic disparities in receipt of predialysis nephrology care at least 1 year before dialysis initiation in the United States from 2005 to 2015.

Design, Setting, and Participants

This national registry study assessed US registry data of 1 000 390 adults in the US Renal Data System who initiated maintenance dialysis treatment from January 1, 2005, to December 31, 2015, in multiple cross-sectional analyses. Multivariable logistic regression models were used to examine national trends in racial/ethnic disparities in receipt of predialysis nephrology care with adjustments for potential confounders. Data were analyzed April 17, 2020.

Exposure

Race/ethnicity of the patients.

Main Outcomes and Measures

Receipt of at least 12 months of predialysis nephrology care as determined by clinician-based documentation on the End Stage Renal Disease Medical Evidence Report Form CMS 2728.

Results

Among 1 000 390 adults (57.2% male; 54.6% White, 27.8% Black, 14.0% Hispanic, and 3.6% Asian; mean [SD] age, 62.4 [15.6] years) who initiated maintenance dialysis in the United States from 2005 to 2015, 310 743 (31.1%) received at least 12 months of predialysis nephrology care. In 2005 to 2007, compared with White adults, the adjusted odds ratio for receipt of at least 12 months of predialysis nephrology care was 0.82 (95% CI, 0.80-0.84) among Black adults, 0.67 (95% CI, 0.65-0.69) among Hispanic adults, and 0.84 (95% CI, 0.80-0.89) among Asian adults; in 2014 to 2015, the adjusted odds ratio was 0.76 (95% CI, 0.74-0.78) among Black adults, 0.61 (95% CI, 0.60-0.63) among Hispanic adults, and 0.90 (95% CI: 0.86-0.95) among Asian adults.

Conclusions and Relevance

In this cross-sectional study of more than 1 million US adults with end-stage kidney disease, racial and ethnic disparities in predialysis nephrology care did not substantially improve from 2005 to 2015. Study findings suggest that national strategies to address racial/ethnic disparities in predialysis nephrology care are needed.

Theory-Based Development of an Implementation Intervention Using Community Health Workers to Increase Palliative Care Use

CONTEXT

Opportunities for the use of palliative care services are missed in African American (AA) communities, despite Level I evidence demonstrating their benefits.

OBJECTIVES

Single-institution and stakeholder-engaged study to design an intervention to increase palliative care use in AA communities.

METHODS

Two-phased qualitative research design guided by the Behavior Change Wheel and Theoretical Domains Framework models. In Phase 1, focus group sessions were conducted to identify barriers and facilitators of palliative care use and the viability of community health workers (CHWs) as a solution. After applying the Behavior Change Wheel and Theoretical Domains Framework to data gathered from Phase 1, Phase 2 consisted of a stakeholder meeting to select intervention content and prioritize modes of delivery.

RESULTS

A total of 15 stakeholders participated in our study. Target behaviors identified were for patients to gain knowledge about benefits of palliative care, physicians to begin palliative care discussions earlier in treatment, and to improve patient-physician interpersonal communication. The intervention was designed to improve patient capability, physician capability, patient motivation, physician motivation, and increase patient opportunities to use palliative care services. Strategies to change patient and physician behaviors were all facilitated by CHWs and included creation and dissemination of brochures about palliative care to patients, empowerment and activation of patients to initiate goals-of-care discussions, outreach to community churches, and expanding patient social support.

CONCLUSION

Use of a theory-based approach to facilitate the implementation of a multi-component strategy provided a comprehensive means of identifying relevant barriers and enablers of CHWs as an agent to increase palliative care use in AA communities.
